Club CassiopeiaNayutan Alien
A song with an intro that starts with a catchy melody, making a strong impact.
For guitar, focus more on rhythm than on the phrases when practicing.
The bass line moves around quite a bit, so make sure to keep a solid beat.
Drums require practice because you need to play the hi-hat tightly to create the right atmosphere.
The vocals are high difficulty in both rhythm and pitch, so you’ll need determination.
Also, there’s a key change in the latter half, so everyone except the drums should be careful not to slip out of alignment.
